Question

How do you find the slope and intercept of `x=4`?

Answer 1

See an explanation below:

Explanation:

This equation represents a vertical line where `x` is always equal to `4` for every value of `y`.

By definition, the slope of a vertical line is undefined.

Because the value of `x` is always equal to `4` the x-intercept is `(4, 0)`

Because the value of `x` is always equal to `4` it is never equal to `0` therefore there is no y-intercept.
